To prevent injuries during physical activities, it is crucial to incorporate warm-ups and cool-downs into every workout. Start with dynamic stretching to prepare muscles, and always focus on proper form to avoid strain. Gradually increase workout intensity to allow the body to adapt, and listen to any signs of discomfort. Additionally, wear appropriate footwear and choose the right equipment for your activity. Staying hydrated and strengthening core muscles can also help in injury prevention, maintaining overall physical health.
